\Header{solve.reStruct}{Apply Solve to an reStruct Object}
\keyword{models}{solve.reStruct}
\begin{Description}\relax
\code{Solve} is applied to each \code{pdMat} component of \code{a},
which results in inverting the positive-definite matrices they
represent.\end{Description}
\begin{Usage}
\begin{verbatim}
## S3 method for class 'reStruct':
solve(a, b, ...)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{a}] an object inheriting from class \code{reStruct},
representing a random effects structure and consisting of a list of
\code{pdMat} objects.
\item[\code{b}] this argument is only included for consistency with the
generic function and is not used in this method function.
\item[\code{...}] some methods for this generic require additional
arguments.  None are used in this method.
\end{ldescription}
\end{Arguments}
\begin{Value}
an \code{reStruct} object similar to \code{a}, but with the
\code{pdMat} components representing the inverses of the
matrices represented by the components of \code{a}.\end{Value}
